Replacing welding quality inspection, parameter adjustment, and troubleshooting tasks; AI automatically identifies defects and optimizes welding processes, reducing technician intervention.
-
Partially replaces assembly technicians in precision assembly, material handling, and simple repair operations; currently in prototype stage but with great potential.
- Routine product dimension and surface quality inspection using measuring instruments
- Manual assembly and fastening of repetitive metal parts
- Operate traditional non-CNC machine tools according to fixed procedures
- Troubleshooting and Repair of Simple Mechanical Faults
- Using AI-assisted diagnostic tools to quickly locate complex mechanical faults
- Equipment commissioning and optimisation via digital twin
- Leverage CMMS for predictive maintenance to reduce downtime
- Collaborative robot programming and maintenance
- Manual adjustment and precision assembly of non-standard equipment
- Flexible decision-making in on-site fault diagnosis and repair strategies
- Reverse engineering and repair of old equipment or equipment without drawings
- Cross-system integration debugging and troubleshooting
- PLC programming and industrial robot operation
- Use of digital twins and CMMS systems
- Sensor and IoT device debugging
- Operation and maintenance of additive manufacturing equipment
- Knowledge of electrical and hydraulic systems integration
